Water is a vital nutrient among all other nutrients i.e.
Carbohydrates, fats, Proteins, vitamins & minerals. Everybody can survive
without these five nutrients but not without water for more than 3 to 5 days.
In other words, water is a life saving nutrient. It constitutes 60% of the
human body weight.
Our Human body derives water from 2 main sources – Drinking Water
and food. A small quantity (about 800ml) of water is formed in the tissues as a
result of metabolism. 6 glasses of water per day is recommended for a normal
healthy person. To know your daily requirement of water, divide your weight (in
ponds) in half and drink this much ounces of water daily i.e if weight is 100
pounds then the daily requirement is 50 ounces of water (1.47 Liters). The
water intake and loss must be equal in order to maintain the normal water
balance.
Excessive water loss (such as that occurs in severe diarrhea) results in dehydration and Excessive Water Retention(such as that
occurs in kidney failure) results in edema.

perspiration.
Transport of Nutrients: It helps in that transport of the
nutrients.
Cell Health: It acts as a carrier that transport chemicals
to and from cells.
Tissue Health: It helps in building and repair of body
tissues

in which all the chemical & metabolic reactions take place i.e. Water also
helps in the breakdown of food.
Absorptions & Digestion: Water helps in absorption of
nutrients from the food we eat and thereby helps in digestion
Elimination of Waste product: After absorption &
digestion, it also helps in removing wastes from the body through urine and
